Anyone install Edlebrock aluminum heads ?

Gears and converter may be your best improvement, but don't change that rpm intake. What is the diameter of your rear tires?
Where are you AJ?
235/60/15. I know a taller tire would help. Id like to change the rpm solely to delete the crossover to an air gap. I installed a wooden spacer and it made a huge difference in how it ran, vapor lock etc. I’m positive it would run that much better if I deleted crossover. I’m also currently working on installing a fuel separator. Fuel regulator set at 6.5 also installed.
